To all whom it may concern;

Be it known that we, J OIiN P. RICHARZ and STEWART Soo'rr, both of thecity of St. Louis and State of Missouri, have invented a certain new anduseful Improvement in Printing-Machines, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Our improvementrelates to a printing machine or press on which bothsides of the sheet are printed atone operation, or by which twoimpressions may be made upon one side at a single operation.

Our improvement also relates to a printing machine or press havingdrying-rolls by which the sheet is heated and dried between theimpressions.

Figure 1 is a side view of the machine, the gearing and heating-pipesbeing omitted. Fig. 2 is a longitudinal. section. Fig. 3 is an end Viewof the feed-rolls. Fig. 4 is a detail side View, and Fig. 5 a top view,showing the coggear connection bet-ween the cylinders and heating'rolls.Fig. 6 is a vertical section at 6 6, Fig. 4. Figs. 7 and 8 arerespectively a longitudinal section and side elevation, showing thearrangement of parts when the machine is used ter the printing of twoimpressions 011 the same side of the sheet of paper.

1 is the main frame of the machine.

2 is a reciprocating typebed containing the fiat type-form by which thefirst side of the sheet is printed. The bed has its longitudinalreciprocation imparted to it by means not shown.

3 is the impression-cylinder that works in conjunction with thetype-form of bed 2. This cylinder is supported on a shaft, 4, that iscaused to rotate by any suitable means. The shaft et carries acog-wheel, 5, that engages a cog-wheel, 7, upon the shaft 8 0f thesecondimpression cylinder 9, as shown in Figs. 1, 2, 3, 4, 5, and 6. Thecog-wheel 7 engages a cog-wheel, 10, upon the shaft 11 of thetypecylinder 12, which carries the type form or plate 13, by which thesecond impression is made on the sheet. The cog-wheel 7 engages acog-wheel, 14:, as shown in Fi 6, upon the shaft or journal 15 of a hotroller or drum, 16, over which the paper sheet passes to dry the ink.The shaft 15 also carries a cog-wheel, 17, that has capacity for endwisemovement on the shaft upon a feather-key or spline, 18, that causes thecogwhcel to rotate with the shaft. 19 is a set-screw passing through thehub of the cogwheel and bearing upon the shaft, to secure the cog-wheelin its position. The cog-wheel 1.7 engages a cog-wheel, 20, upon theshalt or journal 21 of the hot roller 22. The shafts or journals of thehot rollers 16 and 22 are made hollow to allow the pas sage ofheating-pipes 23, through which steam or hot air or water is passed toheat the rollers. The paper sheet is taken by grippers 21 on theimpressioncylinder 3 and carried down over the type-bed 2,where thefirst side is printed. hen the front edge of the sheet comes into theproper position, it is released by the grippers 24' and taken by thegrippers 25 of the second impression cylinder 9 and carried up beneath ahot cylinder or roller, 26, bearing on the second-imprcssion cylinder,whose journal or shalt is made hollow, to allow the passage oi." aheatiug'pipc, 23, as described in connection with the other hot rollers.The sheet is carried forward with the impressioncylinder 9, and betweenit and the form 13, where the second side or imp rcssion is printed. Thesheet is carried over the hot rollers 22 and 16, and as its front edgeis released by the grippers 25, it is taken by the grippers 27 on theroller 16 and carried around this roller until its front edge reachesthe grippers 28 upon the roller 22, when it is released by the grippers27 and taken by those 28, and the sheet is carried on the roller 22, andits edge being released by the grippers 28, it is taken by the fly 29 atthe proper time and laid on the receiving-table, as usual.

It will be observed that the relative diameters of the cylinders 3 and12 is such that the cylinder 12 has two rotations for every rotation ofthe cylinder 3, so that there is only a single sheet printed for tworotations of the cylinders 9 and 12.

To avoid the inking of the tympau-sheet on the cylinder 9, the cylinder12 is moved away from the cylinder 9 during alternate rotations, whenthere is no sheet passing between them. To accomplish this movement ofthe cylinder 12, its journal-boxes 30 are supported in frames 31, inwhich they have movement longitudinally of the machine. Each journal boxor block has a yoke, 32, embracing a cam, 33, whose oscillation givesthe described .movement to the box. connected by a rod, 35, with one endof a lever, 36, fulcrnmed to the frame.

37 is a cam-rod connected to the other end of the lever and working in aguide, 38.

39 is a cam-stud upon the cam-rod, carrying an anti-friction roller thatoccupies the camgroove of the rotary cam 40 on a shaft, 41, havingrotation imparted to it by any suitable mechanism. (Not shown.)

, It will be understood that the mechanism for giving the describedmovement to the cylinder 12 is duplicated upon the sides of the machine.This movement of the cylinder is very slight, not suiiicient todisengage the wheels 7 and 10. v

The course of the sheet of paper through the press when both sides areprinted has been described.

In many cases it is required that one side shall be printed in twocolors. The arrangement of the machine for this purpose will now bedescribed.

42 is a frame movable longitudinally upon the frame 1, having a rack,43, engaged by a cog-wheel, 44, to which rotation may be imparted by ahand crank or wrench.

The following parts have bearing in the frame 42, viz: the cylinders 9and 12, the rollers 22 and 26, the fountain 45, fountainroller 46,vibrating roller 47, and type-rollers 48.

Thejournalboxcs 49 of the roller 16 have bearing in guides 50 concentricwith the cylinder 3, the arrangement being such that the roller 16 canbe raised into the position shown in Figs. 7 and 8 without changing itsdistance from the shaft 4 or cylinder 3. To allow this upward movementof the roller, the frame 42 is moved outward, so as to carry thecylinder 9 away from the cylinder 3.

The roller is raised by means of curved racks 5l,depending from itsjournal-boxes 49,

.said racks being engaged by cog-wheels 52 upon a shaft, 53, extendingtransversely across the machine. hen the roller 16 is in its upperposition, the set-screw 19 is loosened and the wheel 17 moved inwardupon itsshaft, so as to engage with the cog-wheel 5, then the set-screwis tightened. The frame 42 is then moved inward until the cog-wheel 7engages the cog-wheels 14 and 17, so that the wheel 7 is actuated bymeans of the wheel 17 instead of the wheel 5, directly; consequently therotation of both the cylinder 9 and roller 16 are reversed. Thecog-wheel 20 is brought into engagement with the cog-wheel 7. In thiscase the first impression is printed on the sheet, as before described;but the second impression, although printed by the cylinder 12, isprinted upon the same side of the sheet as the first impression.

The cam 33 has an arm, 34,

The course of the sheet through the press is as follows: When the frontedge of the sheet is released by the grippers 24, it is taken by thegrippers 54 of the roller 16 and carried to the cylinder 9, when thegrippers 54 release, and the sheet is taken by grippers 55 and carriedaround between the cylinder 9 and the type-form 13. \Vhen the sheet isreleased by the grippers 55,it is taken by the grippers 28 of the roller22 and carried to the fly, as before.

The paper, in a continuous roll, is shown at 56 supported on a shaft,57, resting on standards 58. The paper from the roll passes firstbetween two feed-rolls, 59 and 60, and then between a pair offeed-rolls, 61 and 62. The fced-rolls 59 and 60 are connected togetherby gear-wheels 63-and 64, and the rolls 61 and 62 are connected in likemanner by gear-wheels and 66, the wheels 63 and 65 being connected by anintermediate pinion, 67.

68 is a cogpinion upon the journal of feedroll 59, that engages acog-wheel, 69, having intermittent rotary motion by means of aratchet-wheel, 7 0, fast to wheel 69, an arm, 71,

vibrating upon the journal or pin 72, and a spring pawl or dog, 73, onthe arm engaging the ratchet-teeth of wheel 70. The arm 71 is slotted toreceive a pin, 74, that is movable in the slot.

75 is a rod passing through an eye in the pin and secured by aset-screw,76. This rod 75 is connected at the other end to awrist-pin,77, secured in the slot of a crank-arm, 78, upon the shaft 4. It will beseen that the rotation of shaft 4 will cause the oscillation of the arm71, and that the more distant the pin 77 is from the center of the shaftthe greater the oscillatory movement of the arm 71 will be. Theoscillatory movement is also increased by fixing the pin 74 near theaxis 72. It must be borne in mind that the pin 74 must always be atleast as far from the point 72 as the pin 77 is from the point 4. Themovement of the feed-rolls is adjusted to suit the length of the sheetof paper being printed, so as to draw the proper amount of paper fromthe roll 56. As the paper leaves the feed-rolls 61 62, it passes betweentwo stationary rolls, 78 79, around which are coiled guide-wires 80,fixed at the other end to the upper and under bars of a frame, 81,through which the paper passes to reach the impression-cylinder 3.Although the rolls 7 8 7 9 are stationary when the machine is at work,they may be turned in their bearings to wind up or let out theguide-wires 80 to suit the length of sheet of paper that is beingprinted. For this purpose they carry cogwheels 82 83, that engagetogether, and the wheel 82 engages with a cog-wheel or pinion, 84, thatis upon a shaft turned by hand. The paper between the rolls 59 and 61passes over a table, 85, having a groove, 86, transverse to themachine,to receive the drop-knife or shear-blade 87. This blade at theproper time is allowed to fall and cut a sheet from the roll. The fallof the blade may be assisted by IIO a spring. It is proposed to set theblade with one end a little lower than the other, so that it shallcommence to cut at this end and cut across the paper to the other end ofthe blade. The blade is fixed to a sash, 88, each end of which isconnected by a rod, 89, to one end of a lever, 90, whose other end isconnected by a rod, 91, to a cam-lever, 92, having an antifrictionroller or wheel, 93, that bears upon the top of a cam, 91:, upon theshaft 4. The arrangement is such that the knife or blade is held upwhile the paper is being fed forward, and descends when the feedingmovement ceases, the wheel 93 dropping from rear end of cam 94. Afterthe sheet of paper has been cut from the roll, and as it is about to betaken from the grippers 24, the roll 62 is lifted from the paper, toallow the same to be freely drawn forward by the grippers 21. For thispurpose the roll 62 is carried on two hinged arms, 95, to each of whichis hinged a rod, 96, whose lower end is connected to one end of a lever,97, the other end of the lever being con nected by a rod, 98, to acam-lever, 99, whose other end carries an anti-friction wheel, 100, thatis acted on by a cam, 101, on shaft 4, to lift the wheel and throw upthe roller 62.

Allusion has been made to the adjustment of the guide-wires 80 in lengthto suit the length of the sheet. As the guide-frame 81 is fixed, it isevident that the rolls 78 79 must be movable. It is also evident thatthe cutting-blade and feed-rolls would have to be made movable for thesame reason. For this purpose the feed-rolls and feed-wheels 69 are,with the rolls 78 and 79 and the cutting mechanism, supported on alongitudinally-movable frame, 102. This is moved by means of cogwheels103 upon the transverse shaft 104 and cog-racks 10?), fixed to the mainframe 1. The shaft 101 being the same that carries the pinion 84, itwill be seen that the rolls 78 79 are turned simultaneously with themovement of the frame 102, and the relative size of the rolls and thecog-wheels is such that the wires 80 are in a stretched condition in allpositions of the frame 102.

The ink-rollers 4S and vibrating roller 47 should be made to move withthe boxes 30 of cylinder 12.

The fountain and fountain-roller 45 46 may be stationary on the frame42.

In place of making the cylinders 9 and 12 movable relatively to thecylinder 3, the former may be stationary and the latter movable; but weconsider the described construction preferable.

The feeding mechanism may be dispensed with, and the sheets of paper fedby hand, as is common. a

It will be seen that if cit-her of the typeforms is removed the pressmay be used to print one side of the paper without any other change,except the removal of the inkingrollers belonging to the removed form.

The feed-board is hinged at 106 and 107, to allow either of its ends tobe lifted to enable the interior parts of the machine to be readilyreached.
